To all whom t may concern.'

Be it known that I, LEO S. RICE, a citizen of the United States,residing at Van Wert, Vin the county of Van Wertand State of Ohio, haveinvented certain new and useful Improvements in Dumping Vehicles, ofwhich the following is a speclcation.

This invention relates to improvements in dumping vehicles.

The primary object of the invention is the provision of a dumpingvehicle cal pable of side and end dumping of the body bed for thepurpose of convenient sition of hauled material.

A further object of the invention is the provision of a-dumping vehicleof the above described character, in which pivoting of the bed fordumping purpose is effected by compression means.

A further object of lthe invention is the provision of a dumping bed forvehicles, which can be manufactured as an accessory to be attached tothe chassis of standard makes of motor trucks.

Other objects and advantages will be apparent during the course of thefollowing detailed description.

In the accompanying drawings, forming a part of this specification, andin which similar reference characters designate corresponding partsthroughout lthe several views,

Figule 1 is a side elevation ofthe imi proved dumping vehicle.

Figure 9 is a fragmentary view, partly 1n section showing details of theactuating means.

Figure 10 isa view partly in section of the device illustrated in Figure9, and taken at right angles thereto.

In the' drawings, wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the letter A designates a vehicleof any approved type, having the special body mounted thereon by themeans C; said means C adapting the body B for pivoting upon the vehicle'A for` dumping purposes. Compreslsion means D is provided, foractuation of the vehicle body B for selective deposit of materialtherefrom.

The vehicle A may be of any preferred type, including a. drivers seat15, and the chassis frame 16.

rIhe body B may of course, be of an design, suitable for transportationof di lferent materials. In the present instance, the body B includes afloor or bed 18; right and left side walls 19 and 20, and forward andrear end retaining walls 21 and 22. As will'be subsequently set forth indetail, the body B is adapted for tipping sideways upon eitherlongitudinal side of the chassis frame 16, as well as for tipping uponthe rear of the chassis frame 16 forend tipping of the vehicle body B.

`Consequently, the side gates 24 and 25, have been provided as a portionof the side walls 19yand 20 respectively, and hinged thereto, as by thehingedI members 26a. It is preferred, that the gates 24 and 25 ybehingedly connected adjacent the top-of the side walls 19 and 20, thusleaving the gates to be swung outwardly from the bottom thereof adjacentthe bed 18. A retaining device 28 has-been provided for regulatinswinging of the side gates 24 and 25, including a pair of arms or rods29 and 30a, pivotally consoV nected to an oscillating lmember or lever31, substantially centrally of the longitudinal length ofv the gates 24and 25. The l rods 29 and 3()a act in the nature of bolts,

' to be locked in position upon the body B.

Cil

The end wall 22 serves the additional purpose of a gate having pivotbolts 23 mounted adjacent the top margin 24a thereof, and upon oppositeends for pivotal reception within bearings 25B, upon the rear end postsci the body B. Thus, the end wall or gate 22 swings outwardlysubstantiallysimilar to the side gates 24 and 25, bolt members 26 beingslidably carried by the gate 22 for engagement in keepers 27, wherebythe gate orwall-22ma be locked in place to form a retaining wa l uponthe body B.

Referrin now to the means C for mounting the -bo y B upon the chassisframe A, cross transoms 30 are positioned at intervals upon the chassisframe 16 of the vehicle A; these transoms'30 being preferably of wood,and of a type in standard use. It will be noted yfrom an observation ofFigure 5 of the drawings that the transoms project considerably fromeach longitudinal member 31 of the chassis frame 16 as is the practicein mounting of vehicle bodies. Transverse bracing sills 32 are atlixedat spaced intervals upon the 'bottom 33a of the bodyV bed 18, forreinforcing purposes. Side rods 33 and 34, preferably circular information, are longitudinally attached to the bottoms of the reinforcinsills 32, and to the left and right sides o the body B l'espectively, asby the detachable bearing clamps 35. It is preferred, that thesupporting rods 33 and 34, be laced parallel of the longitudinal axis oft e body. B, and spaced in. predetermined relation with respect toextending in alignment for pivo'tal'bearingl the longitudinal center ofthe Vbody B. Bearings 36 and 37, are provided upon the leftv and rightoverhanglng ends of each transom 30, and detachably positioned upon theltop surfaces 38 thereof, to provvideA open substantially U-shapedseating pockets 39. The bearing members 36, upon the left side of eachtransom 30, have their pockets 39 of the rod 33. Similarly, the bearingsupon the right side ofeach transom 30, are

Y in alignment to have their pockets 39 piv otally receive the bar 34upon the bodyB.

A substantially U-shaped bar 41 is def tachably connected to the undersurface 33 of the bed 18, extending .transversely of the body B, andmounted immediately over the top surface 38 ofV the rear transom 30.

4position upon a main lead `conduit or pipe 71, extendlng to 12o pivotalreception ofthe bar 41. Pins 47 'l0 or any suitable locking mechanismmay be provided for enga ing the flanges 48 and 49, forming the poc ets39 of the side bearings 36 an 37, the same being provided to preventdetachmentof the longitudinal side bars 33 and 34, from the vehicle A.Likewise, locking pins-50 are provided for en-` gagement with the legs45 and 46 of the end bearing members 43, to prevent accidentaldetachment of the end pivoting bar 80 support' 41. Y

The compression-actuating means D is of novel formation, including apair of cylinders 55 and 56, mounted adjacent the left and right sidesof the vehicle A respectively.

It is preferred that the cylinders'55 and 56 .be mounted substantiallyintermediate the extreme ends of the body B, the exact placing thereofdepending upon the size and re` .quirements of the dumping-.vehicle Eachcylinder 55 and 56 is preferably swivelly mounted for oscillationlongitudinally of the vehicle, having diametricallyl opposed projectinglugs 57` and 58 for engagement in bearings 59, clamped in any suitablearrangement to the chassis frame 16. .A piston 60 is provided for eachcylinder 55'and 56 having a piston rod 61 attached thereto forreciprocation therewith. The upper free end of each piston rod 61 isprovided with 100 spaced arms 62, to provide a yoke structure, vwherebya groove wheel 63 may be rotatably supported thereby.` Track members 65and 66 are provided, upon the bottom surface 33a of the bed 18,transversely of the body B,

and for cooperation with the piston arranoement in the cylinders 55 and56 respectively. VarioustwaysV may of course be provided for actuation othe piston members 50, for

reciprocation thereof to actuate the body B in amannertobe subsequentlyset forth. A hydraulic oil lift system utilizing hydraulic jacks, may beused in this connection. preferred arrangement, however, is that ofcompressed air, been clearly illustrated in the diagrammatic view inFigure 6. A compressed air .tank 70, is preferably mounted in anyconvenient the chassis frame 16, having Lateral feed pipes 73 and 74 areprovided, 125

emanating from the control valve 72, and leading to the cylinders 55 and56 ,respectively. 4Three-way regulating valves 75 are rovided in each ofthe lateral lead pipes 3 and 74 for the purpose of effectively con- 130and the control of which has trolling ow of compressed air into thecylinders 55 and 56. A cross section of one ot the regulating valves isshown in Figure 7. The rotary valve head 76 is provided with apassageway 77 therein. The entrance 78 of the valve 75 having connectionwith the pipe which retain the longitudinal 'sidebar-s 33 7 and 34 1nposltion,

ping of the body B of the cylinders 55 76 of each of the regulatingvalves 75 are so turned that the passageway* 77 of each is in permitpassage of air directly through each valve structure 75, and into thecylinders 55 and 56. When the operator are removed. End tipnecessitatesusing both opens the control valve 72, the compressed air from tank 70will immediately be. directed to the lateral pipes 73 and 74, and intothe cylinders 55 and 56, through the openin s 81 therein. The compressedair, will o course expand in the cylinders 55 and 56, and upon contactwith the piston 60 will force' the same upwardly. As the grooved wheels63 are in firm engagement with the trackways 65 and 66, the same providea bearing which transmits the oompressed air, force to the body B,tipping the same upwardly in' the end bearing members 4 3. Due to theswivel mounting of the cylinders 55y and 56, the same may be readilytipped in their bearings 5 9 to compensate for the angular tipping ofthebody B with respect to the vehic e A. This flexible character o f thecylinders has been illustrated in dotted lines in Figures 1 and 4 of thedrawings. The end gate 22, is of course'swung outwardly to release theload of material in the'body B. When all -of the material has beendumped in the position desired, the compressed air from cylinders 55 and56 is readily exhausted by adjustment of the valve heads whereby thepassageway 77, in valve heads 76 may communicate to release air throughthe lead pipes 73 and 74 to the exhaust openings 80 of these regulatingvalves 75.

The body B canbe tipped from either 'side of the' chassis frame 16. Ifit is desired to tip the body B to the right of the vehicle A, thepins47 holding the longitudinal rod 33 are all detached; as well as thepins 50 holding the end bar 41. The ins 47 holding the rightlongitudinal side Y ar 34 remain in position to lock this longitudinalmember to the chassis frame 16. In tipping the body and 56. The valvehead 7 6v in the regulating valves 75,

B to a side of the vehicle frame A, only one cylinder may be broughtinto use. 'When tipping the body B` to the right as above mentioned, thecylinder 55 must be the actuating cylinder, and vice versa. In actuatingthe cylinder 55, the valve head 76 of the regulating valve 75 forcontrol of compressed air into the cylinder 56 is turned, in such mannerthat the passageway 77 is closed to the entrance opening 78, andpreventing flow of compressed air from the tank'70 to this cylinder 56.The valve 75 of cylinder 55 on the other hand, is opened, so thatcompressed fair may pass from the pipe 71 into the cylinder 55 in themanner above described. When the operator opens the control valve 2, thecompressed air will actuate the piston 60 in the cylinder 55, in themanner above described. In order to provide for the acute inclination ofthe body B when tipped in this manner, the track ways 65 and 66 havebeen provided for'cooperation with the above described rotatingl wheels'63 on the piston stems 61. Thus, 1n tipping the body to the right, thewheel 63 will ride over the rail of the track 65, to compensate forangular disposition of the body B on the vehicle A in tipping position,and thus provide a flexible connection between the piston and the bodyB; In operating the body B to tip to the right side, the same willassume a position,

substantially as illustrated in the dotted lines in Figure 3 of thedrawings. Likewise, in tipping the body to the left side, the

full lines illustrated in Figure 3 illustrated the en'd,.merely by theoperation of valve v controls; in this respect differentiating from thelaborious devices in common use, whereby manual exertion is to a greatextent necessary for tipping of a vehicle body.

Various changes in the shape, size and arrangement'of parts, may be`made to the form of the invention herein' shown and described, withoutdeparting from the spirit of the invention or the scope of the claims.'
